Riverstone Resources has reported that results of 17 drill holes, including ten reverse circulation (RC) and seven diamond core (DD) holes, on the Kao deposit, which is part of the flagship Karma Gold project located in West Africa. These holes are drilled as a part of drilling campaign specifically designed to mine a freshly developing south mineralization zone at Kao deposit.
The company has encountered 17.10 g/t gold over 4 m in DD-12-084, 4.81 g/t gold over 6 m in 11-RC-266, 1.87 g/t gold over 12 m and 2.00 g/t gold over 14 m in DD-12-081, 3.61 g/t gold over 4 m and 1.03 m g/t gold over 14 m in 11-RC-268.
Mineralization found at the Kao deposit expands over 1,400 m toward the northeast-southwest part and at least 900 m down-dip towards the east. These new holes show the occurrence of good grade zones in shallow oxide material, and some deeper intersections.
This drill program has expanded the prominent zone by further 200 m based on visual analysis, and by at least 100 m depending on assay information. The mineralization stays exposed along strike in all directions and also down-dip.
The South Kao zone includes several larger holes, which have been drilled and cut more local quartz veining and sulphides. Riverstone has observed visible gold grains in three holes. Most abundant visible gold is present in a hole drilled at the southern-most segment.
The company continues drilling on this segment and has planned for an additional drill program for one or more segments present towards the south. It is waiting for assays from several holes and will be announced after they become available.
